| Lignan found in bark of some magnolia species. Magnolol (MAG) — a bioactive biphenolic compound from Magnolia officinalis derived from the bark (roots and branches) of Magnolia species such as M. officinalis, M. obovata, and M. grandiflora The two main bioactive compounds isolated from these plants are MAG (5,5ʹ-diallyl-2,2ʹ-dihydroxybiphenyl) and Honokiol (3,5ʹ-diallyl-4,2ʹ-dihydroxybiphenyl) (Fig. 1) which are phenolic regioisomers. In the bark extracts of Magnolia plants, the composition of MAG ranges from 1 to 10%, while Honokiol comprises 1 to 5% Magnolol is a biphenolic neolignan isolated from the bark of Magnolia officinalis. It is structurally related to honokiol and is studied for anti-inflammatory, antioxidant, antimicrobial, and neuroactive effects. In preclinical oncology models, magnolol is reported to modulate NF-κB, STAT3, PI3K/AKT, MAPK, Wnt/β-catenin, and redox pathways, with downstream effects on cell-cycle arrest, apoptosis, invasion/EMT, and angiogenesis. Oral bioavailability is limited and many cytotoxic concentrations reported in vitro are in the tens of µM range, often above typical systemic levels from standard supplementation. major pathways and molecular targets involved in magnolol’s anticancer actions: -Apoptosis: ↑ Bax, ↓ Bcl-2, ↑ cytochrome c, ↑ caspase-9, ↑ caspase-3 -Arrests cell cycle at G0/G1 or G2/M phase:↓ Cyclin D1, CDK4, CDK6, Cyclin B1, CDK1 -Inhibits NF-κB activation: ↓ IκBα, COX-2, TNF-α -Inhibits PI3K, Akt, and mTOR phosphorylation -Suppresses angiogenesis: ↓ Bcl-XL, Mcl-1, VEGF, cyclin D1 -Inhibits β-catenin nuclear translocation -increase ROS production in tumor cells → triggers mitochondrial apoptosis -Magnolol activates Nrf2 in normal cells → upregulates HO-1, NQO1: Protects normal tissue from oxidative stress during chemotherapy or inflammation. Most in-vitro IC50 values fall in the 10–100 µM range, often above typical systemic exposure.

| TP53 is the most commonly mutated gene in human cancer. TP53 is a gene that encodes for the p53 tumor suppressor protein ; TP73 (Chr.1p36.33) and TP63 (Chr.3q28) genes that encode transcription factors p73 and p63, respectively, are TP53 homologous structures. p53 is a crucial tumor suppressor protein that plays a significant role in regulating the cell cycle, maintaining genomic stability, and preventing tumor formation. It is often referred to as the "guardian of the genome" due to its role in protecting cells from DNA damage and stress. TP53 gene, which encodes the p53 protein, is one of the most frequently mutated genes in human cancers. Overexpression of MDM2, an inhibitor of p53, can lead to decreased p53 activity even in the presence of wild-type p53. In some cancers, particularly those with mutant p53, there may be an overexpression of the p53 protein. Cancers with overexpression: Breast, lung, colorectal, overian, head and neck, Esophageal, bladder, pancreatic, and liver. |
